Woo, 8 hours and only 5 gallons to show for it isn't cutting it. I'm moving to a 10 gallon set up and would like ideas by seeing everyone's brew zones.
I don't really have a "rig", but here is a pic of my setup:
HLT on the right, on a natural gas burner. Mash tun in the middle, not fired...just a tun. Boil kettle on the left on a propane burner. I've got a march pump with high temp silicone hose to move fluids around, and a counterflow chiller to get the wort down to pitching temp. More pics of that brew setup and other brewery projects are in my sig.
I heat my HLT on the stove, dump in my cooler, lift the cooler onto the counter, set a bucket underneath it with my boil pot on top of it, and sparge. I then carry the 6.5 gal of wort outside and set it on my burner, then boil. I then cool it and dump straight from the kettle into the fermenting bucket. No fancy stuff for me.
Here is mine. Depending on the length of mash, boil and whether I "no chill" my wort or not, I can get a 5 gallon ale finished in less than 4.5 hours. A more complex multi step lager in 5.5 hours with closed system wort cooling, 90 minute mash and 90 minute boil.
